Detailed explanation-1: -Chemical digestion in the mouth is minor but consists of salivary amylase (ptyalin, or alpha-amylase) and lingual lipase, both contained in the saliva. Salivary amylase is chemically identical to pancreatic amylase and digests starch into maltose and maltotriose, working at a pH optimum of 6.7 to 7.0.
Detailed explanation-2: -Four examples of chemical digestion are amylase in the saliva, hydrochloric acid in the stomach, pepsin in the stomach, and lipase in the small intestine. Amylase is an enzyme in the saliva that begins the process of digestion in the body. It breaks down carbohydrates into their monomers, monosaccharides.
Detailed explanation-3: -Salivary glands secrete salivary amylase, which begins the chemical breakdown of carbohydrates by breaking the bonds between monomeric sugar units.
